Testosterone, a hormone essential to the human body's overall health, plays a role in various aspects of our lives, from muscle mass and mood to energy levels and sexual wellbeing. Regardless of gender, this hormone affects individuals, and low testosterone, often called male hypogonadism, can impact one's overall quality of life.

Testosterone is produced primarily in the testes for men and in smaller quantities in the adrenal. It regulates numerous bodily functions, including the development of male sexual features, such as facial hair and a deeper voice, and promotes muscle and bone growth. It also affects mood, energy, and overall wellbeing.

Low testosterone is characterized by insufficient levels of testosterone in the body. Low testosterone can occur at any age but is more prevalent in older adults, particularly men over 30.

Causes of low testosterone

  • Ageing: The natural ageing process is one of the most common causes of declining testosterone levels. Testosterone production starts decreasing gradually around 30 and continues throughout a man's life. By the time men reach their 70s, they may have lower testosterone levels than in their youth.
  • Hypogonadism: Hypogonadism is characterized by inadequate functioning of the testes in men or ovaries in women. This can be congenital (present from birth) or acquired later due to injury, infection, or other medical conditions.
  • Chronic illness and medical conditions: Various chronic illnesses and conditions can contribute to low testosterone, including diabetes, obesity, metabolic syndrome, chronic kidney disease, and liver disease. The conditions can disrupt the balance of hormones in the body, affecting the production and regulation of testosterone. Chronic conditions like HIV/AIDS and inflammatory diseases can also lead to low testosterone levels due to the body's heightened immune response and the impact on hormonal regulation.
  • Medications: Some medications, especially those used for pain management and certain psychiatric conditions, can lead to low testosterone levels. Opioid pain medications, corticosteroids, and some antipsychotic drugs are known to have this effect. If you suspect your medication affects your testosterone levels, consult with urology doctor for alternative options.
  • Lifestyle factors: Several lifestyle choices and habits can contribute to low testosterone:
  • Obesity: Excess body fat, particularly abdominal fat, is associated with lower testosterone levels. Fat tissue may convert testosterone into estrogen, leading to a hormonal imbalance.
  • Poor diet: A diet lacking essential nutrients, especially zinc and vitamin D, can negatively impact testosterone production. Zinc is a critical component in testosterone synthesis, and vitamin D plays a role in hormone regulation.
  • Lack of exercise: A sedentary lifestyle and lack of physical activity decreases testosterone levels. Regular exercise, particularly resistance and strength training, can help maintain healthy testosterone levels.
  • Chronic Stress: Prolonged stress can increase cortisol levels, which may interfere with testosterone production. Stress management techniques and relaxation can be beneficial in such cases.
  • Environmental factors: Exposure to certain environmental toxins can also affect testosterone levels. Chemicals in some plastics, pesticides, and industrial pollutants contain endocrinedisrupting chemicals that can mimic or block hormones in the body, potentially affecting testosterone production.
  • Genetic factors: Genetic predispositions can influence testosterone levels. Some individuals may have a genetic tendency toward lower testosterone production, making them more susceptible to low testosterone even at a younger age.
  • Pituitary and hypothalamus dysfunction: The pituitary gland and hypothalamus in the brain play essential roles in regulating testosterone production. Any dysfunction in these areas can disrupt the signalling pathways that control the release of hormones involved in testosterone production.

Symptoms of Low Testosterone

The symptoms of low testosterone vary among individuals, and some may experience a combination of these signs more intensely than others. Symptoms include:

  • Reduced libido: One of the most noticeable symptoms is a decrease in sexual desire and interest in sexual activity. Individuals with low testosterone often report a reduced passion for intimacy.
  • Erectile dysfunction: Low testosterone can lead to difficulty achieving or maintaining an erection. Erectile dysfunction can impact the ability to engage in and enjoy sexual activity.
  • Fatigue and low energy: A common complaint among those with low testosterone is persistent fatigue and a significant decrease in energy levels. This may lead to a lack of motivation and feeling tired throughout the day.
  • Mood changes: Low testosterone levels are often associated with mood swings, irritability, and increased feelings of sadness or depression. Individuals may find it more challenging to manage stress and maintain emotional stability.
  • Loss of muscle mass: Testosterone plays a role in muscle development and maintenance. Low testosterone can lead to muscle loss, reduced muscle strength, and decreased physical performance.
  • Increased body fat: Lower testosterone levels are often linked to increased body fat, particularly around the abdomen. This can contribute to a more pronounced "belly" appearance.
  • Reduced bone density: Low testosterone can negatively affect bone health it may decrease bone density and increase the chances of osteoporosis, especially in older individuals.
  • Memory and cognitive issues: Some people with low testosterone report experiencing difficulties with memory, concentration, and cognitive function. This can affect work, daily tasks, and overall mental sharpness.
  • Sleep disturbances: Low testosterone levels can interfere with sleep patterns, leading to insomnia, frequent awakenings, or restless sleep. This can exacerbate feelings of fatigue and irritability.
  • Difficulty achieving orgasms: Some men with low testosterone may experience difficulty reaching orgasm or may notice that orgasms are less intense.
  • Decreased sperm production: Testosterone plays a crucial role in sperm production. Low testosterone may lead to a reduction in sperm count, potentially impacting fertility.
  • Testicular shrinkage: In some cases, low testosterone levels can lead to testicular shrinkage, which may be noticeable and cause discomfort.

Benefits of addressing low testosterone

Addressing low testosterone can have several positive outcomes, including:

  • Improved libido: Restoring testosterone levels can boost sexual desire and function.
  • Enhanced mood: Balancing hormones can lead to improved emotional wellbeing and reduced irritability.
  • Increased muscle mass: Treating low T can help with muscle growth and strength.
  • Higher energy levels: Many people experience increased energy and vitality after addressing low testosterone.

Ways to improve testosterone

Testosterone levels can be improved in two ways: naturally and with medical intervention. Natural approaches like lifestyle changes are suitable for mild cases; medical interventions, including hormone replacement therapy, should be considered when symptoms persist or testosterone levels are clinically low.

Natural ways to improve testosterone levels

If you suspect you have low T, consider these natural approaches to improve testosterone levels:

  • Lifestyle changes: A healthy diet, exercising regularly, managing stress, and getting enough sleep to support optimal hormone levels are crucial to managing low testosterone.
  • Weight management: Losing excess weight, especially belly fat, can help boost testosterone levels.
  • Nutrition: Consume foods rich in zinc, vitamin D, and omega3 fatty acids, as they are linked to testosterone production.
  • Strength training: Engage in resistance and weightbearing exercises to promote muscle growth and testosterone production.

Medical methods of improving low testosterone

Testosterone supplements are used to address low testosterone levels and associated symptoms. They work in various ways to increase testosterone levels in the body, and the choice of supplementation method depends on individual preferences and the recommendations of doctors. Here are different ways testosterone supplements work:

  • Hormone Replacement Therapy (HRT): This is one of the most common methods for increasing testosterone levels. It involves administering synthetic or bioidentical testosterone to the body through various delivery methods, including:
  • Injections: Testosterone injections are administered directly in the muscle tissue, providing a controlled and steady release of the hormone over time.
  • Topical gels and creams: These are applied to the skin and are absorbed into the bloodstream. They provide a consistent delivery of testosterone over the course of the day.
  • Transdermal patches: These patches are applied to the skin and gradually release testosterone into the bloodstream through the skin.
  • Oral tablets: Some oral formulations are available but are not commonly used because of potential liver metabolism issues.
  • Implants or pellets: In this method, small hormone pellets or implants are inserted under the skin, usually in the buttocks. These pellets release a steady supply of testosterone over several months, eliminating the need for frequent injections or applications.
  • Nasal gels and buccal systems: Some testosterone supplements are administered through nasal gels or buccal systems (applied to the gums). These methods provide alternative options for individuals who prefer noninvasive routes of administration.

The choice of testosterone supplementation should consider the individual's health, underlying conditions, preferences, and the risks and benefits associated with each method. Additionally, regularly monitoring testosterone levels is essential to ensure that the chosen method effectively increases testosterone to a healthy range and that any potential side effects are promptly addressed.
